Both Scotch® Super Glues and Scotch® Multi-Purpose Glue bond many substrates, but super glue dries much quicker. Generally, Scotch® Super Glues are stronger than Scotch® Multi-Purpose glue, but not in all cases. Multi-purpose glue is ideal for use on paper, poster board, cardboard, wood, fabric, metal, aluminum, formica, vinyl, PVC and acrylic. Super glue is commonly used for gluing wood, metal, leather, ceramic, rubber, some plastics and similar materials. Super glue is usually not a good choice for paper.
